MFStools2.0 boot CD boot options error?

I noticed that the mfstools2noJ.iso image has the following boot options described in message.txt

swap DMA disabled, byte-swapping enabled.
dmaswap DMA enabled, byte-swapping enabled. (Dangerous)


specified in the isolinux.cfg file:

label swap
kernel vmlinuz
append hdb=bswap hdc=bswap hdd=bswap
label dmaswap
kernel vmlinuz
append hdb=bswap hdc=bswap hdd=bswap


the two labels specify the exact same configuration, which the description says is dangerous. shouldn't the "swap" option specifiy the vmlnodma kernel, not vmlinuz? while because of the mutually exclusive DMA/bswapping device options, the two may end up being the same for drives hdb, hdc, hdd, it would not be the expected behavior for all drives after that (they WOULD have DMA if option swap is chosen).
